While selecting fields for a Candidate Import in Taleo Connect Client, I noticed a small red icon next to a few of the fields. (IE: EmailAddressValidated, Applications,Number)
What does the red sign icon next to a field mean in Taleo Connect Client?

A red circle means this field's properties cannot be changed via Taleo Connect Client.
Important Note: While you can't update the field's properties, you can update the value of this field with a TCC import.
